Abstract Here we describe a new pterosaur footprint assemblage from the Hwasun Seoyuri tracksite in the Upper Cretaceous Jangdong Formation of the Neungju Basin in Korea.The assemblage consists of many randomly oriented prints in remarkably high densities but represents a single ichnotaxon, Pteraichnus.Individuals exhibit a large but continuous siz
The pathogenesis of chronic apical periodontitis (CP) is almost clear today.This enables to perform causal therapy [1,2, 3, 5, 6].Proper root canal treatment and obturation prevent development of CP.If CP is present at the time of treatment, it usually heals up.Additional surgical intervention is required very rarely.CP as a frequent coincidental f
The CFETR multi-purpose overload robot (CMOR) is a key subsystem of the remote handling system of the China fusion engineering test reactor (CFETR).This paper first establishes the kinematic and dynamic models of CMOR and analyzes the working process in the vacuum chamber.Based on the uncertainty of rigid-flexible coupling, a CMOR adaptive robust s
Abstract Energy conditions, especially the null energy condition (NEC), are generically imposed on solutions to retain a physically sensible classical field theory and they also play an important role in the AdS/CFT duality.Using this duality, we study non-trivially deformed strongly coupled quantum field theories at large-N c.The corresponding dua
